Abstract (en)
[origin: EP1731496A1] The present invention provides a method for efficiently using an aqueous solution of (meth) acrylic acid at a low concentration formed in a production/storage step of (meth)acrylic acid. In the present invention, a (meth)acrylic acid derivative is produced by using as a raw material an aqueous solution of (meth)acrylic acid formed by one or both of: a device which reduces a pressure of a gas comprising (meth) acrylic acid in production of (meth) acrylic acid; and a device which collects (meth)acrylic acid from a gas comprising (meth)acrylic acid.
